To all whom it concern: 7 Be it known t all, FRANK ENGLISH, e A citizen of .the United States, z'es idin at Fresno, inehe county of Fresno and tote e of Golifornia;havein-venterl new end. useful Improvements in Lift-Pumps, of which the follows log is a. specification.

This invention relates to lift pumps, and

A seci 5 load to clille 'eni points on e column or level of the well and a valved tube Q1 similar to tubes 19 and suspended in the same manner extends into the water 22 of the Well.

The controlling valves ISinoy be of any suitslfie'arrangement; their function be'in to intermittently open the suction pipesv the upper end enrl'one of the pi es 5' commumeites at one side.

As shown in Fig. 3, flier valves comprise each a chamber .23 Wish, Whichone of the pipes 12 communicutes'eii-fi 2 9 9 r l; the loweu nor-io'iouof fiche chamber is on opening 2% foe colzclnunicetionvvith theotmosphei' A re;

In the present; immnee; "X show an outside ci'enk arm 1K3 and 5 are exerting s suction the for housing the volvefio and all five crei'ilc 1 arms 26 are connected to a single rod 2? which in mm connects with one arm of e: bell crank lever 28, the other arm of which.

in operation, and assuming the pump is roperly primed end that the controlling valves for pipes 1, 3 and 5 are in positiou ho permit the vecuum to act) on the letter,

then the pipe 5 will fill its compartment with Water through the tube 21 from thewell :;lielow and pipe'B will fill its compartment mm the compartment below and pipe 5 will fill lrhe pump head from the top ost. In the mean time, pipes 2 and e are openio the atmosphere and no resistance is ofiereci to the depletion of their compertiiients by the overlying suction pipes.- In

colnpartthe atmosphere.

inediately the suction pipes have filled their compartments the controlling valves are so timed as to be actuated. and quickly reverse their position so that pipes 2 and a are now OD' tllG vacuum and 1, 3 and 5 are open to Thus water is lifted from compartment to compartment in successive stages, making possible the pumping of the water from greatly increased depths and in greater volume. r i

The head 1% preferably discharges by gravity through a flap valve 3+1. The purpose of having the tubes 19 and 21 suspended from bevel seated heads, each of a different diameter, is to permit easy removal of these parts. Each tube is shown as having a bail at its 11) er and. to )ermit a rab hook to engage it whereby to lift the tube and head from the shaft. The fact that the apertures in the partition plates 17 increase in diameter from bottom to top permits these beveled heads from below to pass through the overlying partition plates quite readily.

The elbow 16 is detachable from the pump head and shaft, and is, of course, removed when it is desired to lift the tubes from the shaft as above explained.

Various changes in the construction and arrangement of the several parts hereiir shown and described may be employed without departing from the spirit of my invention' as disclosed in the appended claims.

Having thus described my invention, What I claim and desire to secure by Letters Pat out is: p r l. Inaliftpump,a shaft divided throughout its length into separate compartments, a vacuum tank, a vertical series of outlet pipes leading froni'the tank, a vertical series of valves connected to the pipes, suction conduits connecting the valves to the respective compartments, and adapted to be alternately connected to the respective outlet pipes and the atmosphere through the essons 3. ln av lift pump, a shaftdivided througlr out its length. into a plurality of separate compartments, each comprising an annular partition plate fixed in said shaft, a head having a beveled seat within said plate, a tube suspended from said head and a valve in said tube, and suction means communicating with each of said compartments.

at. In a lift pump, a shaft divided through out its length into a plurality of separate compartments, each comprising an annular partition plate fixed in said shaft, a head having a beveled seat within said plate, a

tube suspended from said head and a valve in said tube, suction means communicating with each of said compartments, said bevel seated members being of' decreasing diam eter fronitop to bottom and means Whereby the suspended tube and head may be engaged by a grab hook to lift the' same upwardly through the shaft.

In testimony whereof I have hereunto set my hand in the presence of tWo subscribing witnesses. FRANK ENGLISH. ll itnessesz M. A. McCARrnY, A. W. CAntsoN.
